Sea Watch Foundation Marine Megafauna Sightings (1930 to 1970)

The Sea Watch Foundation has been collecting both effort-based and non-effort-based sightings data of marine mammals and other megafauna since the late 1960s. The main area of coverage is the waters around Britain and Ireland but with some surveys elsewhere. Data come from platforms ranging from small to large vessels either on dedicated survey or platforms of opportunity, and from coastal land sites. Data collected include environmental conditions, marine traffic, and seabird associations. Sighting records come from all types of marine user from marine mammal biologists to citizen scientists and members of the public. All sightings are checked, and species ID validated from still or video images and/or descriptions, except in those cases where persons are known, experienced, observers.

海洋观察基金会（Sea Watch Foundation）自20世纪60年代末以来，一直收集海洋哺乳动物及其他巨型动物群的基于努力（effort-based）和非基于努力（non-effort-based）目击数据。其主要覆盖区域为英国与爱尔兰周边水域，但也包含其他地区的部分调查数据。数据来源广泛，包括从小型到大型的船只（无论是专门调查船还是机会平台（platforms of opportunity））以及沿海陆地观测点。收集的数据涵盖环境条件、海上交通及海鸟伴生情况。目击记录来自各类海洋使用者，从海洋哺乳动物生物学家到公民科学家及普通公众均有涉及。所有目击记录均经过核查，物种鉴定通过静态或视频图像及/或描述予以验证——已知的经验丰富观测者的记录除外。
